Question

If the object is moving, it is possible for the net force acting on it to be zero? Explain.

Short answer

Yes, when the object is moving with a constant velocity, the net force on it must be zero.

Step-by-step solution

Step 1. By Newton’s second law

The acceleration of an object is directly proportional to the force applied to it.

Step 2. Case of an object moving with uniform velocity

If an object is moving with uniform velocity, its acceleration must be zero. From Newton’s second law, you know that acceleration is directly proportional to force and follows the relation$F=ma.$

Here, m is the mass of the object, F is the force applied, and a is the acceleration.

Thus, acceleration being zero implies that the net force will also be zero. Therefore, it is possible that the net force on a moving object is zero.
